The Hung Shun Tong manuscript is a handwritten booklet including the organizational rules, rituals, instructions, discipline, and secret signals between members of the Hung Shun Tong (also known as the Society of Heaven and Earth).
This manuscript was written in 1886 with Cantonese dialect and is an early primary source documenting the organization of this Chinese secret society and its operation in northern California in the 19th century.
